Title: Consumable electrode welding power source
Inventor: MINOOKA MASAHIRO
IPC: B23K9/067
Filed: 1989-04-17
Abstract: PURPOSE:To prevent a buckling accident of a welding wire by detecting the presence or absence of a welding current by a welding current detection circuit and detecting the presence or absence of a short circuit of the wire by a short- circuit detection circuit to stop the wire feed or change its feed rate. CONSTITUTION:At the time of starting welding, an output control circuit 13 sends an output signal of slowdown conditions lower than at the time of steady- state welding to a wire feed motor 12. When the welding wire 11 comes into contact and short-circuits with material 10 to be welded, a welding current detection signal A outputs a state of the presence. At the same time, a wire short-circuit detection signal S outputs the wire short-circuit. A wire output stop signal output circuit 16 receives the foregoing two signals and stops the motor 12. When this state continues, an arc is generated and the short-circuit signal S is changed to noncontact and the output control circuit 13 outputs an output signal M to the motor 12 so as to rotate under steady-state welding conditions. Since the wire feed is stopped till the wire is heated and molten sufficiently, the buckling accident is prevented.

Title: Jam detecting circuit for printer paper
Inventor: HIRAMA YUKIHIRO
IPC: B41J15/00
Filed: 1980-07-17
Abstract: PURPOSE: To provide a low cost and highly reliable printer paper jam detector, whose reponsive speed is appropriately slowed by providing a feedback circuit which varies current passing through a luminous diode.  
     CONSTITUTION: In case where reflectivity of a paper 3 (hole-free section) is excellent, the output current of an amplifier 16 is small, the output of a phototransistor 1b is adjusted to an almost constant value, and the output of a comparator 10 is also low. When a feed hole 2 of the paper 3 appears, the output of the phototransistor 1b becomes small rapidly, and the difference from reference voltage VRE of a differential amplifier 14 becomes large, and by functions of minus feedback connection of a resistance 13 and a capacitor 12, the output of the differential amplifier becomes large gradually, and at the same time, a luminous diode 1a becomes light, and the output of the phototransistor 1b becomes constant. Then, when it moves to a section where there is no hole, the output of the phototransitor 1b becomes suddenly large, and the output of the differential amplifier 14 becomes small slowly. Natural control is performed in this fashion, without requiring adjustment of the luminous diode, so that the output of the phototransistor becomes a constant pulselike wave.
